The answer to your question would be space. The sun's light travles through space. but if you clap, you can't hear it.
Answer:
The answer is B. Vacuole
Explanation:
Assuming the image is something I've already seen, & with the question being familiar, I do remember the answer being Vacuole.
The nurse will explain to the client is
the catheterization will visualize the disease process in the coronary arteries.
A cardiac catheterization delivers information on how well a heart
works, recognizes problems and allows for procedures to open blocked
arteries.
For example, during cardiac catheterization your doctor may:
<span>
Gather
up samples of blood to measure the oxygen content in the four chambers of
your heart.
<span>Take X-rays using
contrast dye injected over the catheter to look for narrowed or blocked
coronary arteries. This is known as coronary arteriography or coronary
angiography.
</span>
Assess
the ability of the pumping chambers to contract.
Look
for deficiencies in the valves or chambers of your heart.
Execute
a percutaneous coronary intervention (PCI) such as coronary
angioplasty with stenting to open up narrowed or blocked segments of
a coronary artery.
Check
the compression in the four chambers of your heart.
Remove
a small piece of heart tissue to examine under a microscope (biopsy).</span>
Answer:
pests can evolve defenses against pesticides over time
Explanation:
Pesticides are chemicals employed to kill pests generally. With continuous and indiscriminate use of pesticides, they become less effective because pests population often evolve a defense mechanism against them.
<em>With each usage, more and more pest population survive. Those that survive gradually multiply and pass the survival gene to their offspring eventually giving rise to a population that is genetically insusceptible to the effects of the pesticide. This is generally referred to as evolution by natural selection.</em>
Answer is Homologous.
A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.
Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.
